What Causes Sudden Jerking While Driving the Envision?
1 Answers
Possible causes include carbon buildup in the throttle body; clutch failure; or transmission control module programming issues. Carbon buildup in the throttle body: Carbon deposits in the throttle body can cause abnormal engine air intake, leading to unstable engine RPM. This prevents the transmission control module from quickly shifting gears, resulting in jerking motions. The throttle body needs cleaning to remove carbon deposits. Clutch failure: A faulty clutch increases resistance during gear shifts, causing jerking movements. The clutch requires replacement. Transmission control module programming issues: Faulty programming in the transmission control module can cause incorrect gear shift logic, leading to jerking. The transmission control module software needs updating.
